IMPROVBD APPARATUS FOR THE MANUFAGTUBE Ol? SDDA-WATER, AND FOR AERATING LIQUIDS.

TO V.ALL WIIOM IT MAY CONCERN: v

Be it known that I, `JOHN MATTHEWS, Jr., of the city, county, and State of New York, have invented a new and useful improvement on Apparatus for the Manufacture of Soda-Water and for other Purposes of Aeration, of which the following is a full, clear, and exact description, reference being had -to lthe accompanying drawing, forming part of this specification.

This invention consists in so constructing an apparatus for-'the manufacture of soda-water and for other purposes of aeration, but which will here be described for manufacturing soda-water, as that the pump-feed and agitator to the condenser may bc connected therewith without the establishment of joints to the latter, above .the average level of the water. therein, by operating the feed and agitator through the base or lower portion of vthe condensorgslilzewise in running. the discharge or feed pipe from the pump into the condenser, and giving arecipro'cating action therein,- by or with the pump, in'su'ch manner as that the pressure of gas or liquid in the eondenseris made'to'assist the pump, in its discharging or feeding stroke .to the condenser, by acting upon the exposed end of said discharge pipe or devices connected therewith; also in combining with the lreservoir or 'com denser a pump 'for charging and keeping up the supply to theA latter, having for its constituent parts a lower stationary hollow'plunger and reciprocating cylinder, with suitable inlet and delivery valves and upper reciprocating discharge or' feed pipe, whereby great simplicity of working parts is effected, and a steady guiding action secured to the pump; and furthcrmore, said invention consists in arranging, on the end or portion of the discharge pipe which projects into the condenser from below, one or more volutes or their equivalents, constructed so as in the reciprocating action bf the pump to catch and distribute the gas in the water, and to agitate the latterfwithin the condenser fori the purpose of cti'ecting a thorough mixing of-the gas and water. Referring tothe accompanying drawing, in whichi Figure 1 represents a sectional elevation of. an apparatus constructed according to this invention applicable to themanufacture of and dispensing of soda-water.

Figure 2, anoutside elevation ol the same, seen at right angles to fig. 1; and

Figures 3 and 4, inverted plans of rcci'prpcatinglvolutes used for mixing the gas and water in the reservoir or condenser. l

A are uprights or portions of the general frame, the same being suitably braced or connected, and carrying a table, B, at their top, on which is secured the condenser or reservoir C for holding 'the carbonio acid gas and water mixed. therein, and which reservoir, by the present improvement, is or may be free from all joints below its water line, the average level of the latter being indicated, say, by the line a in icr. 1. Inserted through the table B may be tubes for attachment oi' the usualbottling-nipple and pressure-gauge or safety-valve.

Connected with the frame, at or near its base, is a stationary hollow plunger, D,'co imnunieating below bya branch, b, with a valve-box,jE, the valve c of which isarranged to open upwards, and controls tho suction by a passage, c?, with or through branches cf, the one of which serves as the induction pipe for the water, and the other for the carbonic acidigas from any suitable reservoirs or vessels. F is the working cylinder, which plays.

up and down over or outside-of the stationary plunger D, and is connected to so as to he operated by a reciprov eating yoke, G, dirivcn, say, by nnylsuitablc power through a crank, H, having play in an oblong slot of the yoke. This cylinder F is provided,at its` upper end or portion, with a delivery-valve, 7L, which, in the descent of the cylinder, allows of thegas and water entering in the up stroke of said cylinder through or beneath the valve C, the plunger Dto be forcibly expelled through a branch, l, and vertical discharge-pipe J, by .perforiln 'tions S into-the reservoir C. The plunger D and cylinder F act as a guide below to this reciprocating arrangement,while the pipe J, working through a stuliingsbox, z', in the table B enbase of the reservoir 0,' operates as an upper guide thereto. K is a cock or valve for shutting off communication between the pump and reservoir.

"C, when necessary for repair of the valves or otherwise, while said reservoir is fu'll or under pressure. The Vgas and water forced out through the perforatiens S, in or during the action of the pump, it is preferred toadmit into the reservoir C, or water contained therein, and to eii'ect themixture of the gas and water by means of any desired number of volutes L M, carried by the reciprocating discharge pipe l where it projects 4within the reservoir C, the one volute L, say, causing the gas as it rises to work spirally outwards, and, passing up into or under the4 upper and larger reverse volute M, to be worked lin an opposite direction or -spirally inwards, and

casts 2 t finally 'escaping by a central orifice. In -this way an eii'eetual agitation is kept up and thorough mixing of the gas with the Water produced by the volutes asthey are worked up. and down within the reservoir C. Any other suitable description of agitator, however, if preferred, may be employed in connection with'thc arrangement'or combination of parts hereinbefore described, or certain of them; and, here it maybe observed, that in some eases, instead 'of the gas .beingr forced linto the reservoir C by the pump,l along with the water, the glas may be separately admitted under pressure to Said reservoir from'its generator, and the water only be forced in by the pump.

Among the advantages which are claimedV for the improvement here described may be mentioned, dispensing Withallljoints above the'water'level inthe reservoir C, the importance of which will be readily understood, whenthe great pressure of the gas contained in the reservoir is considered, and the diliculty that consequently exists to making 'a joint above the water-level tight against escape of gas;- liken'se that the pump is aided in its descent or discharging stroke into the reservoir C by the pressure of the gaslol gas and water contained.- therein acting on the head ofthe disch-argc pipe or agitator reciprocating within said reservoir; thus the pump is aided in producing further compression or condensation by the pressure previously eiiected by it, or, where the pump is merely usedto force in thc-water, the same is assisted in supplying thc'rcservoir C by the pressure of thelg'as separately admitted thereto. l

I In addition to these advantages may be mentioned the great simplicity ot` the working parts and steadiness of action, as produced by the reciprocating cylinder F on the plunger D and discharge pipe J, into and through the bottom of the reservoir, the distance apart of the guides to the pumpaiding in this' result, and the reciproeating action of the pipe or connection -J i'n a longitudinal direction being prcferableto a rotary one 'for working the agitator, as offering greater security against leakage at the stuiiing-box. I-Iere it maybe repeated, however, that any suitable agitator may 'be employed, and such need not necessarily be work-ed by the discharge-.tube ot" the pump; thus a rod might be substituted for the pipe J to work the agitator, 'and the pump-feed to-tho eon-' denser be established by a flexible tube connecting at a-diiierent point with the'eondenscr, either directly through its bottom or through' its side near the bottom, below the water level, such lateral arrangement also, it' desired, being adopted for operating a suitable agitator. It is preferable, however, to make one stuffing-box v -o'r joint serve both for the working of the agitator and pump-discharge into the condenser. Instead of a stationary hollow plunger a working one and stationary cylinder may be substituted for, the pump-arrangement shown in the drawing, with like eilect in many respects at least, in which case, it' desired, the discharge pipe J may connect so as to reciprocate with the'plunger instead of the cylinder, suitable communication being established through said plunger with the pipe J. A

What I claim a's my invention, and desire to secureby Letters Patent,v is- 1. A soda-water or other aci-ating apparatus, having its pump-feed and agitator or mixer, so arranged in relation to its condenser or reservoir, as that all joints in the latter above its average water level may be dispensed with, as'herein speeiiied. p A

2. In soda-water or other aerating apparatus,vthe combination with the reservoir or condenser C -of a reciprocating discharge pipe or tube J to the pump, substantially as andfor thepurpose or purposes herein set forth.l l

2. The combination of the stationary hollow plunger D, reciprocating pump-cylinder F, reciprocating discharge pipe J connected therewith, receiving and delivery-valves, and reservoir or condenser C, essentially as specified.

4. The volutes L.M,or their equivalents, acting as agitator-.s or mixers, arranged on the reciprocating pump-discharge pipe where it projectsinto tllereservoir C, or otherwise similarly driven for action therein, as set forth. v

5. The combination with the pump, for direct action thereby, of an agitator or agitator-s Within the condenser.
